Specification of Letters Patent.

Patented Nov. 7 28, 1905.

Application filed January 12, 1905- Serial No. 240,756.

To all whom it may concern.-

Be it known that I, WILLIAM H. BROWN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Dust-Guards forRailway- Cars, of which .the following is a full, clear, and exactdescription, reference being had to the accompanying drawings.

The object of this invention is to prevent the dust which is stirred upfrom the roadbed by a moving car from flying onto the rear platform ofthat car, to the discomfort of the passengers thereon.

The invention consists of a hood secured upon the car-roof at the rearefid thereof and having an open front end and a downturned spout-likerear end which is substantially as wide as the car and is directed sothat air which enters the front end of the hood will be dischargeddownward at the rear end of the platform, thereby forming a down-flowingcurtain of air which will prevent the dustladen air behind the car fromflowing forward onto the rear platform,all of which will be hereinafterdescribed, and pointed out definitely in the claims.

In the drawings, Figure 1 is a side elevation of the rear end of arailway-car. Fig. 2 is a rear end view of said car; and Fig. 3 is asectional rear view of the upper part of said car, the section being inthe plane indicated by line 3 3 of Fig. 1.

Referring to the parts by letters, A represents a car of any common orsuitable construction. a indicates the roof of said car, and (0' itsrear platform.

B represents a hood which is secured upon It is preferably made of sheetmetal, and it is open at its front end I), so that as the car movesforward air will be taken into said front end. The rear end B of thehood is downturned in the form of a sort of a flat spout which is madeabout as wide as the car-platform and is opened at its lower end, whichend is above or'slightly behind the rear end of the rear platform. Whenthe car is in rapid motion, comparatively clean pure air will be takeninto the opened front end of the hood. This air will flow out of thecontracted spout-shaped rear end of the hood and will flow downward,thereby creating a down-flowing shield or curtain of pure air whichprevents the air filled with the dust stirred up by the car from theroadbed from flying forward onto the back platform.

Having described my invention, I claim- 1. A dust-preventer forrailway-cars comprising a hood secured to the car-roof and extendingdownwardly over the end thereof, there being air inlet and dischargespaces at the front and rear of said hood.

2. A'dust-preventer for railway-cars comprising a hood secured to thecar-roof and curving down over the end thereof substantially in linewith the end of the platform, there being air inlet and discharge spacesat the front and rear of said hood.

3. A dust-preventer for railway-cars comprising a hood which is securedupon the rear end of the car-roof, and is open at its front and rearends, said rear end being in the form of a downturned spout whichextends crosswise for substantially the width of the platform, wherebythere will be discharged at the rear end of the platform a strongcurrent of air taken in at the open front end of said hood.

In testimony whereof I hereunto aifix my signature in the presence oftwo witnesses.

WILLIAM H. BROWN.
